PIN DESCRIPTIONS

Power Supply Connections

VA+ - Positive Analog Power, PIN 3.

Positive analog supply. Nominally +5 volts.

VA- - Negative Analog Power, PIN 5.

Negative analog supply. Nominally -5 volts.

AGND1, AGND2, AGND3 - Analog Grounds, PINS 1, 4, 25.

Analog ground reference.

VD+ - Positive Digital Power, PIN 16.

Positive supply for the digital section. Nominally +5 volts.

DGND - Digital Ground, PIN 17.

Digital ground for the digital section.

Analog Outputs

VREF- - Voltage Reference Output, PIN 28.

Nominally -3.68 volts. Normally connected to a 0.1

µF ceramic capacitor in parallel with a

10

µF or larger electrolytic capacitor. Note the negative output polarity.

AOUTL - Analog Left Channel Output, PIN 2.

Analog output for the left channel. Typically 4V peak-to-peak for a full-scale input signal.

AOUTR - Analog Right Channel Output, PIN 26.

Analog output for the right channel. Typically 4V peak-to-peak for a full-scale input signal.
